Referring now to the drawings, the refer ence character designates a'group, oflogs which are preferably"03E composition.v mate;

f rial. The group may comprise any suitable number of logs. In the form of the device selected to illustrate one embodiment of the invention the group comprisesa front'log 11, a pair of back logs 12am 13, and'a'pair r of intermediate logs 14c and 15 arranged at an angle to 'eachother. The group of logs- 10 are merely shells representingportions of as" small pieces of glass or othertransparent "F or translucent materlal like eoalsof fire; As shown, one or more elec Lilli-i i-Inorder tothe'obseryensee 7 mg: thejllrinteriorfpll-r oi .thedQVlCGimStm PPS 27 9 f? logs, but for convenience of description they Will be termed logs. These logs forni- With the bottornwall lfi'and the rearwall I7=an inclosure19 Within which the light bulbs;

heating elements, light 'intercept'ers and the like, may be positioned. The logs 14 and 15 con-verge upwardly and rearwardly to form a space between them and the front log ,11, which is adapted to be i bridged by supportwhich may be of any suitable material for permitting light'to pass througln such as the Wire mesh 18" orv the like. The wire inesh'18 is adapted't'o support particles- 21 of a diaphanous material such Suitable means are provided-for illn n'ii} natingthe particles- 21 to cause them to glow tric' light bulbs 22' are employed for this purpose, only one being ,shoWn.' The bulb is preferably of red glass, or-the source of light a is such as toemitred rays,'in order to make theparts illuminated look more nearlylike w fire. The bulb is placed in such a position as to illuminate the glass particles 21. i Some of the particles '21 may be of material or. darl'zer'color than the'remainder' to simulate f coals of-fire which vary brightness; j

-r In order to enhance therealistic appearance other particles 230 f diaphanousmm terial maybe secured to the surfaces of the logs 14; and 15 adjacent to the particles 21 and v so arranged that they are Visible by an ob server in front of the device. These parti- I cles may-he illuminated-by andelectric light "bulb 24 arranged in front of an elongated slot 25 in the rear "upper portion oflthe front I log 1'1. The bulb 24: may be elongated and preferably emitsr'ed rays of light for causing" the particles 23 tosglowasfthough" the logs 1 4 and15-wereafire g W r desired, the logs may be proyide'd with v 'aplerturesor slits 26 through: which the red light iromFbulhsQQahd 24: shines, 'gi ving logs the appearance of burning; These slits HITe-arranged-to represent depressions in-the" of translucent material such as celluloid or mica are secured across the slots on the interi'or of the logs.' These strips permit sufiicient amount of the red light to pass therethrough to cause the logs to have the appearance of burning.

One ormore light reflectors and intercepter devices .28, maybe and preferably are provided for intercepting and reflecting the light from the light bulbs to simulate the flickering of a Wood fire. The light'intercepting de- Vices 28 are rotatably mounted onarms 31 V secured to the back panel 17 as clearly shown in Figs. 2 and 8 of the drawings. 7 The light intercepters are placed abovethe light bulbs whereby the heated air rising from the'bulbs will cause the intercepters to rotate, thereby intermittently intercepting the light rays, thus causing the light passing therethrough to simulatethe flickering offiames. The rear wall 17 preferably though not necessarily terminates short of the log 13 so that light fromthe bulb 22 shining through the The heating element may be large enough for heating purposes or it maybe aheating element of small capacity and used merely to add an element of realism to the imltatlon In Fig.4 is showna modified form or coni struction in which the electric log is composed of asingle log 33 having a recess 34 therein in Which the particles-of broken glass or other diaphanous material 21 may be supported as in the constructions described above. The log isihollow as in the previous construction for receiving thelighting heating and light intercepting elements. Since the back 17 and be omittedu;

bottom 16 are the same as the back and bottom of the form shown in Figsl to3and arearrangedin the same manner, it is not thought necessary to further describe or illustratethe same;

It has beenproposed to'usediaphanous materialjin a. metallic coal grate-and illuminate the same from beneath, but such an arrangenecessary that provision be made for supporting the particles 21 in an exposed position.

In use, the device is placed on andirons which also adds to the realistic appearance of the logs and fire. V 1

If desired, the heating element may be located in the upper portion of the log or logs, slits. or apertures being provided through which theheat may be radiated forwardly 7 into the room. V

It is thought from the foregoing taken in connection with the accompanying drawings that the construction and operation of my device will be apparent to those skilled in the art, andthat various changes insize, shape, proportion and details of construction may be made without departing from the spirit and scopeof the appended claims. 7 r I I claim as my invention-z 1. In combination, group; of logs cornprising front, back and intermediatelogs, the intermediate logs being arranged at'an angle to each otherand forming with said front log atriangular space, said front log having a slit opening upwardly and rearwardly, re-

ticulated material extending upwardly and rearwardly across said space, a pluraity of particles of diaphanous material covering said reticulated material and supported thereby, a source of light for illuminatingsaid particles from beneath the same,-anda source of light for illuminating the uppermost 'portions of said particles and portions of said intermediate'logs through said slit.

*2. In combination,a hollow body compris 1 ing. a group of imitation logs simulating a woodfire, saidlogs havinga space among the same, each log having slits-therein, certain of said logs having glass particles'partially embedded. therein, a diaphanous support in sa1d space, a plurality'of diaphanous objects on said support, a source of light within said hollow body, a rotating member op'erated'by air currents for intermittently intercepting a portion of therays projected on said diaphanous" objects from said {source of, light, and means forilluminating said glass articles through certain of said slits.
